Oana Balalau

I am a researcher (ISFP) at Inria in the CEDAR team and part-time assistant professor at École Polytechnique. I am part of LabIA, a government initiative to bring the benefits of AI to public administrations. Previously, I was a postdoctoral researcher at Max Planck Institute for Informatics in the team of Gerhard Weikum. I received my PhD from Télécom Paris and my advisor was Mauro Sozio.

My research interests are in natural language processing, graph learning, and computational social science. I accept reviewing for open-access conferences and journals.

PhD candidates:
Kun Zhang (2021 - present), co-advised with Ioana Manolescu.
Tom Calamai (2022 - present), co-advised with Fabian Suchanek.
